This paper details the results of a series of large-scale experiments, conducted by the U.S. Bureau of Mines, where small coal fires were used to ignite conveyor belting at air velocities ranging from 0.76 M/s to 6.1 M/s. Two nomographs are presented, which define sensor alarm levels and sensor spacings as a function of belt entry cross-sectional area and belt entry air velocity.
